1. Mirayiridzo yekushandiswa kwesero tsika ndiro
Petri ndiro dzinowanzo gadzirwa negirazi kana epurasitiki, uye dzinowanzo shandiswa sezviyedzo zvekushandisa pakurima tupukanana kana sero tsika.Kazhinji, ndiro dzegirazi dzinogona kushandiswa kugadzira zvinhu zvekudyara, hutachiona hutsika, uye hutsika tsika dzemasero emhuka.Iyo plastiki zvinhu inogona kunge iri polyethylene zvinhu, iyo inokodzera murabhoritari inoculation, scribing, uye mabhakitiriya ekupatsanura maoparesheni, uye inogona kushandiswa kurima zvirimwa zvezvirimwa.Petri ndiro hadzina kusimba, saka dzinofanirwa kubatwa nekungwarira panguva yekuchenesa uye kushandiswa.Mushure mekushandiswa, dzinofanirwa kucheneswa nenguva uye kuchengetwa munzvimbo yakachengeteka uye yakagadziriswa.
2. Kuchenesa kwePetri ndiro
1.） Soak: Nyura mitsva kana yakashandiswa girazi nemvura yakachena kupfavisa uye kunyungudutsa zvakabatanidzwa.Usati washandisa glassware itsva, ingoikwesha nemvura yepombi, wozoinyika mu5% hydrochloric acid usiku hwose;Iyo inoshandiswa glassware inowanzo ine mapuroteni akawanda nemafuta, izvo zvisiri nyore kutsvaira mushure mekuoma, saka inofanira kunyudzwa mumvura yakachena pakarepo mushure mekushandiswa kwekutsvaira.
2.） Kukwesha: isa girazi rakanyikwa mumvura yekugezesa, uye bhurasha kakawanda nebhurasho rakapfava.Usasiye makona akafa uye kudzivirira kukanganisa kwepamusoro pekupedzisira kwemidziyo.Shamba uye woomesa girazi rakacheneswa kuitira pickling.
3.） Pickling: Pickling ndeyekunyudza midziyo iri pamusoro mumugadziro wekuchenesa, inozivikanwawo se acid solution, kubvisa zvinogona kusara pamusoro pemidziyo kuburikidza neoxidation yakasimba ye acid solution.Kunhonga hakufaniri kudarika maawa matanhatu, kazhinji usiku hwose kana kupfuura.Ngwarira pakuisa nekutora midziyo.
4.） Rinsing: Midziyo mushure mekukwesha uye pickling inofanira kugezwa zvizere nemvura.Kunyangwe midziyo yakashambidzwa yakachena mushure mekunhonga inobata zvakananga kubudirira kwesero tsika.Nekushambidza kwemaoko emidziyo yakakanyiwa, mudziyo wega wega unozodzokororwa "kuzadzwa nemvura - kudururwa" kanenge ka15, uye pakupedzisira kunyoroveswa nemvura yakanyungudutswa ye2-3 nguva, yakaomeswa kana yakaomeswa, uye yakarongedzwa kumira.
